I think that programming is splitting into several different fields. Some of it is rather like 1920's electrician jobs, which by the way were good middle class jobs that people could be proud of being able to do. But other kinds of programming are not blue collar yet. I think it's rather like how electrical engineering and electrician split into separate fields; it's not like electrical engineers ceased to exist, it's that now you people who could actually specialize in doing electrical work.
